i have seen when liquid helium is poured on a magnet, a second magnet can be kept hovering or pulling/pushing each other at will, Is it possible using this technique to design an engineless transportation system?

The real question:
So then why is it when someone goes into the car, the windows fog up. When the heater is on, it gets worse. Turn on the A/C and it clears it right up... How is that??

I know it seems like a funny and silly question but, I am serious! lol.

When we hold a book, our hands are holding it against the gravitational force of the whole earth (WHOA!) which has only been made possible by the electrostatic force between the charged constituents of our hand and the book at the surface in contact.

I know electromagnetic force is intrinsically so much stronger than gravity and that's what keeps us from collapsing.

But, shouldn't the electrostatic forces cancel out each other as the book and our hand are *almost* electrically neutral?

And even if they don't, why is electrostatic force *in this particular case* always negative (Attractive)?

There HAS to be an answer because gravity hasn't collapsed my chair or me yet. What force counters gravitational attraction? What makes it work in the opposite direction of gravitational attraction?

How did you like the question?

A recent study in Biology Letters has shown that a mutation causing a silent chirping in crickets has been spreading rapidly in a hawaiian cricket population.

http://www.newscientist.com/article.ns?id=dn10121&feedId=online-news_rss20

The article comments on what may happen in the future, but doesn't mention the possibility that the crickets with the flatwing mutation will eventually constitute a separate species from those that remain able to call.

This seems like a perfect example to me of what may promote speciation in a population. Am I missing something?

why is bio-degradable plastic made out of corn starch costlier than regular plastic. as the prices of corn starch is much lower than prices of crude oil.

Is it possible to understand the incompletness theorem by Kurt Goedel if I`m not a mathematician, and is there a good book that explains it well?

Thanks for answering
